I have installed Version 7 Internet Security in Windows 8 Customer Preview.The Store app doesn't work because the Firewall won't let it through.I can turn the Firewall off for 10 minutes and then it works.

How do I get Avast to ask me if it is ok for the Store app to have internet access so I can easily fix the problem?I tried to add application to the list of program allowed but it didn't work. Must have done something wrong.
